Attenuators are used in a variety of applications to reduce the power of the signal being sent. The AT-1910(40) is one example of a passive attenuator that can be used to reduce the amplitude of a signal. It is designed to have an insertion loss of 40 dB, with a VSWR of 1.7:1. This makes it ideal for use in low power applications such as radio transmission.

The AT-1910(40) attenuator is a high-performance device that operates in the range of 1.45 GHz to 2.2 GHz, making it suitable for many applications in the microwave field. It is made of an aluminum alloy housing and consists of two copper elements: a short section of an air-dielectric core and a metalized dielectric element. The air-dielectric core has a very low inductance, and hence provides low loss, while the metalized element ensures a high impedance and a stable 50 ohm termination. The AT-1910(40) attenuator also features a unique “window” design, allowing for the user to easily adjust the amount of attenuation.

The working principle of this attenuator is relatively simple. The signal is first sent into the short section of the air-dielectric core, which allows the signal to pass through relatively unimpeded by the low inductance. The signal then passes into the metalized dielectric element, which provides the desired attenuation. Because the metalized dielectric element offers a high impedance, the signal is able to pass through it without any significant changes in amplitude. The 50 ohm termination ensures that the output signal is properly terminated with a stable impedance, and the adjustable “window” allows for the user to easily adjust the amount of attenuation that is necessary.

The AT-1910(40) attenuator is a valuable tool for reducing the signal strength of a radio transmission without sacrificing signal quality. It is ideal for use in low power applications such as radio transmission due to its 40 dB insertion loss and 1.7:1 VSWR at frequencies from 1.45 GHz to 2.2 GHz. Its high impedance also allows the signal to pass through without any significant changes in amplitude, and its adjustable “window” allows for the user to easily adjust the amount of attenuation that is necessary. Overall, the AT-1910(40) is an excellent choice for attenuating a radio signal in low power applications.
